Heh. From the original Usenet posting that suggested the capability
that was added in the form of "setdefault":
| I suggest a minor change: another optional argument to
| "get" so that
|
| dict.get(item,default,flag)
|
| is equivalent to
|
| if dict.has_key(item):
| VALUE IS dict[item]
| else:
| if flag: dict[item] = default <-- This is all that's new
| VALUE IS default
|
| but presumably more efficient.
The response was a chorus of people saying "Not a bad idea, but
that flag sucks. It needs a separate method." :-)
